The microwave spectrum of the chain isomer of disulfur difluoride: FS-SF

On vibrational force field calculations

“…The sign error for the torsion B matrix elements, mentioned above, has 39. Units: F matrix elements in aJ A-' , eigenvalues in aJ A-l u-I, frequencies in cm-', the eigenvectors (L matrix elements) for the mass weighted normal coordinates in u-'", the eigenvectors (L matrix elements) for the dimensionless normal coordinates in A, and P.E.D.…”

“…This is an interesting molecule; it rearranges to form a more stable pyramidal S==SF2 isomer at room temperature (38). The vibrational analysis of this molecule was recently described (39). The atom numbering, geometry, and internal and symmetry coordinates are given in Table I11 of ref.…”

“…The atom numbering, geometry, and internal and symmetry coordinates are given in Table I11 of ref. 39. The output from the UBMAT routine is shown in Table 1, and from the GCALC routine in Table 2 …”

Conformational Equilibria and Molecular Structures of Model Sulfur–Sulfur Bridge Systems: Diisopropyl Disulfide

“…The Fourier transform microwave (FTMW) spectroscopic technique can yield accurate information on molecular structures and conformations. Disulfur dichloride, disulfur difluoride, dimethyl disulfide, and disulfane were early studied examples by Stark modulation MW spectroscopy. Recently, FTMW spectroscopic investigations on dialkyl disulfides have been extended to diethyl disulfide and diphenyl disulfide .…”

Disulfide Bond in Diethyl Disulfide: A Rotational Spectroscopic Study

“…Experimental − and theoretical − efforts have been devoted to investigate the conformational preferences and structures of dialkyl disulfides. Vibrational spectroscopy, , electron diffraction, and rotational spectroscopy ,, have been applied to investigate the structures and conformations of dimethyl disulfide.…”
